Title: Golf cart
Inventor: JIKIBA YASUHIRO
IPC: A63B55/60
Filed: 1999-04-21
Abstract: PROBLEM TO BE SOLVED: To prevent the wrong operation of a steering by the influence of the magnetic field of a brake motor or the like to prevent the meandering by setting the pulse width modulation frequency for controlling the brake motor or the like so that its integer-multiplied frequency is largely different, compared with the frequency of a guidepath wire. SOLUTION: In a passenger golf cart, induction currents carried in loop lines buried along a traveling path are detected by lateral induction sensors 10 in automatic steering mode, and a microcomputer 2 performs a steering control so that a guidepath wire is regularly located in the center of the induction sensors by rotating a steering motor 12 to the right when a left slippage is detected and rotating the steering motor 12 to the left when a right slippage is detected. At this time, the pulse width for driving the steering motor 12 is duty controlled by PWM (pulse width modulation) method according to the slippage. The integer-multiplied frequency of the PWM frequency for controlling the steering motor 12 or the like is set sufficiently large than the guidepath wire frequency.

IPC: H04W88/02
Filed: 1996-05-08
Abstract: PROBLEM TO BE SOLVED: To surely detect whether or not a main power supply battery is inserted to a holder in the radio calling receiver where a secondary battery output is supplied via a DC/DC converter. SOLUTION: Two positive terminals 2A, 2B electrically isolated when no battery 1 is inserted to a holder are provided. Then the positive terminal 2A is connected to a secondary battery 5 to be connected to an input side of a DC/DC converter 6 and the positive terminal 2B is connected to a battery detection terminal of a CPU 4. Through the construction above, when the battery 1 is extracted from the holder, since the positive terminal 2B is separated from the secondary battery 5, the absence of the battery 1 in the holder is surely recognized from a voltage of the positive terminal B.

Title: Tree introducing net-like body
Inventor: SUGIYAMA JIRO
IPC: E02D17/20
Filed: 1996-04-10
Abstract: PROBLEM TO BE SOLVED: To prevent a hindrance to growth of a tree by arranging rust prevention unprocessed parts in a part of meshes of a wire net laid on a slope face to form soil dressing of a thick layer. SOLUTION: When a wire net 1 is formed of iron wire rods 2 on which rust preventive processing is performed by zinc plating or the like, unprocessed parts 4 to which zinc plating is not performed are arranged in a part of meshes. Next, the wire net 1 is laid on a slope face, and soil dressing of a strong organic thick layer is formed by spraying a vegetative base material by blending a seed and a fertilizer or the like upon it. Next, the net wire 1 settles the soil dressing of a thick layer by holding strength for several years after execution work, and when a seed grows into a tree, the unprocessed parts 4 are corroded, and the meshes 3 are easily broken down. Instead of this, a net-like body is formed of corrosive fiber on which antibacterial processing is partially performed, or is formed of anticorrosive fiber to which fragility is partially imparted, or is formed by knitting and weaving corrosive fiber and anticorrosive fiber. Therefore, flowing-away and frost heaving of soil dressing of a thick layer can be prevented, and a tree can be sufficiently grown.

Title: Motion interpolating device
Inventor: JINNO YOSHIYUKI
IPC: H04N19/423
Filed: 1989-05-08
Abstract: PURPOSE:To improve the traceability of a motion and continuity in the plane of an image by selecting a motion vector detected in an area when it is evaluated that the motions of two images coincide with each other visually, and setting a value at zero when it is evaluated that noncoincidence is obtained. CONSTITUTION:A motion evaluation circuit 14 evaluates the motion which coincides with a visual sense, for example, by calculating the difference of a preceding image and a succeeding image stored in memories 11 and 12, respectively, and evaluating the motion vector between the preceding and succeeding images is significant as transmission information when the absolute value of the difference is larger than a threshold value, and evaluating that it is not significant when the absolute value is smaller than the threshold value. A motion vector processing circuit 15 sets the value of the motion vector at zero when the motion vector shows a large number though it is evaluated that the motion vector is not significant by the motion evaluation circuit 14. Thus, since the motion vector is preserved only in an area where the motion is detected visually, the same traceability as that of the interpolation of an ordinary motion can be attached, while, linear interpolation is performed in the area where the motion is hard to be detected visually, and the continuity in the plane of the image can be secured.
